| Research Abstract |
Preload stress echocardiography was applied with leg-positive pressure (LPP) in patients with mild heart failure. Patients were classified into 3 groups based on transmitral flow velocity pattern: restrictive or pseudontrmal (PN) at rest, impaired relaxation (IR) at rest and during LPP (stable IR), and IR at rest and PN during LPP (unstable IR). All-cause cardiac event rate was higher in unstable IR than in stable IR, and was similar in PN group. Event-free survival was lower in unstable IR than stable IR. Preload stress echocardiography provides additional prognostic information in mild heart failure patients beyond conventional echocardiographic parameters.
